摘要： Manufacturing variable and/or singular property products, such as a tubing, in a tip-and-die assembly (51), where intermittent acting material injectors (53a, 53b) are used. Two or more injectors (53a, 53b) take turns making material shots to maintain a continuous material stream. A singular flow controller (54) regulates the flow for all material streams coming from the injectors (53a, 53b).

摘要： A medical device comprising an elongated tube having a proximal section and a distal section, said tube having an annular wall with an outer surface and an inner surface that defines a central passageway that extends substantially the length of the tube, said tube being constructed of a first material and a second material having less stiffness than the first material, the wall of the tube gradually changing from the first material to the second material to form a transition section between the proximal section and the distal section, the first and second materials being gradually combined in the transition section and naturally adhering to each other to form a wall gradually changing from one substantially made up of the first material to one substantially made up of the second material to form a continuous unbroken tube of materials having different properties and without abrupt joints, the distal section being made of the second material and therefore less still than the proximal section.

摘要： Differential stiffness tubing for medical products, such as catheters, and a method and apparatus for making the tubing. The tubing has a stiff section and a flexible section joined by a relatively short transition section in which the materials of the stiff and flexible sections are wedged into each other in a smooth gradual manner to produce an inseparable bond between the materials without abrupt joints. The tubing is made using a resin modulating system and a unique co-extrusion head that minimize the length of the transition section by minizing the volumes in all flow channels of the head.

摘要： A fofdable and restrainable cable for electrical and electronic devices. The cables are preformed with bends to allow the cable to be gathered together easier for bundling. The cable also has a restratner section at one end to hold the cable together after it is gathered and bundled for storage.
